14.8 Virtual servo amplifier function
This function executes the operation virtually without connecting servo amplifiers
(regarded as connected) by setting "4097, 4128" in servo parameter "
Pr.100
Servo
series
". The synchronous control with virtually input command is possible by using the
virtual servo amplifier axis as servo input axis of synchronous control.
Also, it can be used as simulation operation for axes without servo amplifiers.

The details shown below explain about the "Virtual servo amplifier function".
[1] Control details
[2] Restrictions
[1] Control details
(1) When "4097, 4128" is set in "
Pr.100
Servo series
" set in the flash ROM, it
operates as virtual servo amplifier immediately after power supply ON.
(2) When "0" is set in "
Pr.100
Servo series
" set in the flash ROM, it operates as
virtual servo amplifier by setting "4097, 4128" in "
Pr.100
Servo series
" of
buffer memory and by turning the PLC READY signal [Y0] OFF to ON after
power supply ON.
(3) Do not connect the actual servo amplifier to axis set as virtual servo
amplifier. If the servo amplifier is connected, the LED display status remains
"Ab." and the servo amplifier is not recognized. The following servo
amplifiers cannot be connected until the end station.
(4) The current feed value and machine feed value of virtual servo amplifier are
as follows.
(a) When the absolute position detection system is invalid
The both of current feed value and machine feed value are set to "0".
(b) When the absolute position detection system is valid
OP is established: Address at latest power supply OFF
OP is not established: "0" (Feed current value and machine feed value)
(5) When the virtual servo amplifier is set in the system setting of GX Works2,
"0: Disabled (incremental system)" is set in "Absolute position detection
system (PA03)".
Set "1: Enabled (absolute position system)" to the buffer memory to use as
absolute position system.
